Lattice

Security checks for vulnerabilities and agentic risk

Overview

The Lattice read workflow fits its purpose, but its setup fallback runs downloaded installation code without verification or a separate approval step.

Review and approve the CLI installation separately before allowing the agent to run it, including any changes to installed agent skills. Prefer a fixed release with verified integrity. Use only necessary Lattice permissions and consider OOMOL's access to workplace data. The sole bundled artifact was fully inspected, but the external installer and CLI implementation were not verified.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code performs remote installer execution rather than Lattice search or read operations. Nothing in the chunk establishes this installer as a necessary supporting component for Lattice access. The downloaded script's contents are not supplied, so its subsequent actions cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The curl-to-bash command executes a mutable remote script without verifying its integrity or authenticity independently of HTTPS; the PowerShell alternative has the same weakness. If the distribution endpoint or release process is compromised, executing this fallback could run attacker-controlled code with the invoking user's privileges, exposing local data and credentials.

Content

Scanner excerpt · SKILL.md (reported line 62)May include surrounding context.

The setup workflow instructs the agent to execute downloaded installation scripts without warning the user about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback instructs installation through immediate execution of downloaded code without first explaining the system changes or obtaining user approval. Although limited to a missing dependency, this expands a Lattice read request into local software installation; the declared oo-only tool allowance may constrain execution but does not make the installation instructions safe.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
